Suggested Answer: B, D

These two options are the benefits of deploying OAuth in a Cisco UCM environment that uses Cisco Jabber or Cisco Webex for on-premises calling. OAuth is an authorization protocol that allows users to grant access to third-party applications without sharing their credentials. In a Cisco UCM environment, OAuth allows Jabber and Webex clients to obtain access tokens from UCM after authenticating with their credentials once. The access tokens can then be used to access various resources, such as call control, voicemail, directory, and presence. The access tokens have a limited lifetime, but they can be refreshed using refresh tokens, which have a longer lifetime. This way, the users do not need to re-authenticate frequently and can enjoy a seamless user experience. Reference:

Option C seems the most logical choice to prevent toll fraud. Allowing only specific domestic long-distance area codes seems like the best way to control outgoing calls.
